FOOT-PEDAL FOE no'romonirnns.

Specification of Ilctters intent.

ncense.

he principal object of the invention to i provide a dual control mechanism whereby one pedal may be made to do the work of two, as for instance in the case of an autoedal mechanism of such construction that 1t will perform two distinct operations at the will of the driver such as the operation of the gasolene throttle and the mulfier cut out. By this means it will be unnecessaryto move the foot from one device to another as is now necessarily customary where two pedals are used.

Obviously this will result in a saving of space inall foot controlled mechanism and increase the eiiiciency of operators by the consequent saving of time.

These objects are fully accomplished by the novel structure described in the following specification and illustrated in the accompanying drawings, in which, Figure 1 is a fragmentar sectional view of an automobile dash wit my improved pedal in place thereon.

Fig. 2 is a top plan view of a pedal. Fig. 3 is a view similar to Fig. 1 but showing the component parts of my invention in a different position.

Fig. 4 is a side view of a floor plate castof same.

Fig. 6 is a bottom plan viewofsame.

Fig. 7 is a top lan view of same.

Fig. 8 is an on view of same.

Fig. 9 is a front elevation of a lever.

Fig. 10 is a side elevation of same.

Fig. 11 is a side view of an elbow lever.

Fig. 12 is an end view of same.

Referring to the drawings, Fig. 1 indi- Gates a pc a1 casting adapted in size and shape to receive the sole of a shoe. The pedal 1 is provided with a depressed heel portion 2 so arranged that the heel of a shoe on the operator will be arrested from for ward movement by a vertical wall 3. A guard 4 surrounding the rear of the heel and Fate-uteri duty 1%, 1919'.

Application filed mate 1, 1917. Serial 1%. screen for a distance forward on each side prevents, the heel from sliding oil the pedal real wardly or in a sidewise dircctiui'n- In the under surface of the oadal .i is a square mortise 6 to receive the lead "I oi a lever 8 pivotally attached to said pedal 1 by a pin 9 extending through holes in the side walls of the pedal 1 and through a hole 11 in the lever B, and secured by a cotter pin 12. Y

The lever 8 extends downwardly through a rectangular szot 13, in a floor plate casting 14 secured by screws 16 to the dash 17.

The boltoin surface of the casting 14 is prov ded with downwardly projecting walls 18 and It integral therewith and forming guidcs' lor the lever 8.

The lever 8 is pivotally connected at its lower end by a pin 21 to one end of an elbow lever 22. The pivot pin 21 extends through a hole 23 in elbow lever 22 and through either of two similar holes 2-1- in the lever 8 and is secured by a cotter pin 26.

The elbow lever 22 is pivoted at its elbow on a pin 27 extending through a hole 28 in said lever and also through a hole 29 in wall 19 of floor plate casting 14;. V

It will be seen from this construction that the lever 22 will he vibrated as shown in dotted lines in Fig. 3, when the lever 8 is depressed by the pedal 1.

In order to limit the amount of said depression in lug 31 is cast integral with lever 8 for preventing its further entrance into slot 13.

' The lever 22 is provided with a series of holes 32 in any suitable one of which is one end of a coiled tension spring 33, the oppo by spring 33 will yieldably support the lever 8 in the position shown in Fig. 3, Where the edal 1 may be vibrated as shown in dotted ines, and when the operator desires he may depress the pedal 1. bodily and thereby vibrate the lever 22.

The lever 8 is provided with a notch 3-2 for engaging, when said lever is depressed, the under surface of the floor plate 14 (as shown in Fig. 1) and hold said lever in Said depressed position because of the tension of spring 33 until such time as the operator pushes the edal 1 forward far enough to release notci 34 from engagementwhenit will return to position shown in Fig. 3.

Ill)

It is possible to vibrate the pedal 1 inde- 'pcndcntly in either of'the positions shown of the series of holes 32 and leads to mufiler cut out or any desired part of the car. It will be seen'that either the rod- 37 or the cables 38 may be operated independently.

What I claim as new andwish to secure by Letters Patent is A dual control pedal mechanism comprising a pedal pivoted near its center on a bar slidable in a slot in a floor'plate, said bar provided with a lug to limit its movement in engaging the nether snrfaceor' said floor date. the said bar ada )ted when de )rcsscd to vibrate an elbow lever pivoted at the elbow to a portion of said floor plate and one member of said elbow lever provided with a plurality of holes for engaging one end of a coiled tension spring, the opposite end of which is suitably connected to the floor carrying the floor plate, the said spring adapted normally to keep the said notched bar in engagen'ient with the floor plate, a lug on one end of said pedal for securing one end of a connecting rod and holes in one member of said elbow lever for connection with one end of a connecting rod or cable.

In testimony whereof I aflix my signature.

HAROLD A. VAN VALKENBURG.
